Minimax Presents Fire Protection for Wind Turbines

At the on-site HUSUM Wind trade fair in Germany, Minimax will be presenting, until this coming Friday, its fire protection solutions that are tailored to the special requirements of wind turbines

The amount of renewable energy in electricity consumption is growing steadily: At 23.7%, wind energy provided the lion’s share of gross electricity consumption in Germany. Meanwhile, the hydrogen economy, along with wind energy – especially offshore wind energy – is gaining ground. For more than 20 years, Minimax has been protecting these indispensable energy suppliers with approved and certified fire protection technology – both onshore and offshore.

Early fire detection: Minimax aspirating smoke detector AMX4004
The core of reliable fire protection is the early detection of fire and combating it by applying a fire extinguishing process without delay. Our answer to ensuring this happens is the aspirating smoke detector AMX4004. It can withstand vibrations and high fluctuations in temperature as well as extreme climatic conditions. It detects fires as they arise by continually extracting air samples from the monitored area. In conjunction with intelligent evaluator algorithms, a comparison of typical disturbances takes place prior to setting off the alarm, meaning that the AMX4004 is extremely foolproof.

Fire detection and extinguishing control systems
The fire protection and extinguishing control systems from Minimax processes fire detection signals like those of the aspirating smoke detector AMX4004 or the flawlessly operating UniVario flame detectors using cutting-edge technology. They activate programmed control processes such as shutting down the wind turbine, notifying a constantly manned position as well as setting off the extinguishing systems.

Inert-gas extinguishing systems: environmentally friendly and no residue
The Minimax Oxeo Intergas extinguishing systems enable fire suppression adapted to sensitive and high-end facilities such as wind turbines. Inert gases are not electrically conductive and are non-toxic to humans, as they are a natural component of ambient air. They do not cool down and suppress fires without leaving a residue as well as being environmentally friendly. Normally, nitrogen is used in wind turbines but argon or mixed gases may also be used.

Water mist suppression systems: Minifog ProCon
Minifog water mist suppression systems reduce to a minimum the amount of water needed to combat fires. Special nozzles produce a very fine mist enabling the extinguishing agent to be distributed with a larger surface area: The ensuing cooling and suppression effect puts out any possible fire exceptionally quickly. Antifreeze in extinguishing water enables this method to be used at temperatures as low as –30 degrees Centigrade. The amount of extinguishing agent released is so small that normally no additional extinguishing agent retention devices are required. The extinguishing equipment, including the containers with the extinguishing agent for special applications, comes as a compact very lightweight unit that can be easily installed in the wind energy system.

New Fluorine-free Foam Extinguishing Agent

Minimax switches thyssenkrupp Steel Europe Fire Protection Systems to Fluorine-free Foam Concentrate

In May, Minimax and its competence team ‘Steel’ carried out a series of tests with fluorine-free foam concentrate at MPA Dresden GmbH, an independent fire protection competence center. The reason for the efficacy tests, which were supervised by VdS Schadenverhütung GmbH, was conducted at the request of our customer thyssenkrupp Steel Europe AG to convert its extinguishing systems to a fluorine-free extinguishing foam. All the tests were successful, and VdS approved the use of the new, 1% fluorine-free foam extinguishing agent for the protection areas and system types concerned. 

Legal background
Time is of the essence: On April 8, 2020, the EU Regulation 2020/784 was passed, further restricting the use of PFOA (perfluorooctanoic acid). Admittedly, firefighting foams are still considered to have a special status because every fire that can be prevented means that other, incalculable environmental damages are averted. The transitional period until July 4, 2025 still applies to fire extinguishing foams that are already filled in existing systems or mobile extinguishing equipment. From this date onwards, mixtures or products must not contain more than 25ppb (=μg/kg) of PFOA or a total of more than 1000ppb11 (=1ppm=1mg/kg) of all precursors. PFOA foams will no longer be allowed for educational purposes, and for testing only if there is a possibility of capturing all releases. As early as January 1, 2023, use will only be permitted at sites where all releases can be captured. 

What needs to be done?
As a result, many operators are concerned about the future of their fire protection facilities and would like to see a switch to fluorine-free foams. However, a number of requirements has to be considered in terms of the switchover: The VdS recognition for the use of foam extinguishing agents in water extinguishing systems according to VdS CEA 4001 and VdS 2109 always refers to the recognized foam agent and defined applications. If the intended area of application (type of system / fire load) is not already covered by the proof of effectiveness from the acceptance procedure, additional proof of efficacy needs to be provided. In this case, the foam concentrate was already certified for risks associated with plastics. The testing has since been carried out for certain flammable liquids. 

Tests
In May, Minimax conducted extinguishing tests for thyssenkrupp Steel Europe at MPA Dresden GmbH. The parties involved were VdS Schadenverhütung as the testing and certification institution, the risk manager, the foam agent manufacturer Dr. Sthamer, the operator, and Minimax with its competence team ‘Steel’ and the extinguishing system management ‘Water’. 

The configuration of the tests was prepared at length and tailored to the specific application. For the tests, Minimax installed both a deluge system and a water mist suppression system matching the real conditions of the existing system in terms of sprinklers, operating pressures and distances to the fire object. The extinguishing of three selected flammable liquids was tested, each using water and foam extinguishing agents. 

Successful result
The effort was worthwhile: VdS approved the tested foam agent for use in the given types of systems in combination with the three examined flammable (hydraulic) liquids and for use in accordance with the protection concept as per VdS CEA 4001 (sprinkler systems), VdS 2109 (deluge systems) and VdS 2108 (low expansion foam extinguishing systems). 

For Marcel Esper, Head of the Minimax competence team ‘Steel’, and Thorsten Gieseke, Minimax suppression system manager, the results of the extensive extinguishing tests are even more far-reaching: "Beyond the approval, we gained a lot of additional knowledge that we will take into account for the further procedure with fluorine-free foam agents." The competence team ‘Steel’ is the specialist for stationary fire protection in the steel industry, providing single-source support in the Ruhr region for the plants of thyssenkrupp Steel Europe AG, among others. 

For thyssenkrupp Steel Europe AG, the switch to fluorine-free foam concentrate is a particular concern, both to ensure fire protection and, at the same time, to contribute even more to environmental and water protection. The fact that this can be achieved with comparatively little effort means enormous potential savings for the customer. Converting the plant would incur costs and, on the other hand, production would be impaired during conversion periods.

Fendium mit Red Dot Award

Minimax receives Red Dot Award for polymer-enhanced Fendium pipe

Fendium: Award-winning Surface Refinement

Once again, a Minimax product has been honored by the Red Dot jury. This year, Minimax received the coveted award in the “Materials and Surfaces” catgeory for the innovative Fendium pipe system. 

Fendium is a polymer-enhanced steel pipe, coated on the outside and inside with a special polymer that protects against corrosion. In contrast to a painted or powder coating, this polymer protection is built up in a multi-step chemical process. Independent research has confirmed that the polymer achieves extremely high resistance to corrosive influences. Fendium is approved by VdS Schadenverhütung and certified by FM Global. This means that it can be used for nearly all water extinguishing systems.

Michael Steinhoff, Technical Product Manager at Minimax Viking Research & Development GmbH, sees the Red Dot Award as confirmation of the concept: "It was an interesting journey – from the idea to realization and series production. Finally, we created a product, unique on the fire protection market, offering numerous advantages. Apart from the process we developed and now apply, there is currently no alternative process known to coat pipes industrially from the inside. The Red Dot Award in the "Material and Surfaces" category confirms the uniqueness of our product."

Sustainability through a longer service life
When used as intended, Fendium pipes have a significantly longer service life than pipes that have not been treated on the inside.

Consistent higher safety level
In standard pipes, corrosion can lead to rough surfaces, encrustations and deposits which, in turn, increase pipe friction and reduce the free cross-section of these standard pipes. With their internal and external corrosion protection, Fendium pipes increase the effectiveness and reliability of extinguishing systems over the long term and reduce the risk of nozzles becoming clogged up.

Greater efficiency
The low pipe friction offered by smooth Fendium pipes even makes it possible, in many cases, to use smaller nominal diameters or smaller pumps. The advantages include weight savings, easier installation and reduced space requirements.

MXOne High-Performance Firefighting Turbine

Innovative fire protection using water mist from a safe distance

Today, Minimax is launching the extinguishing turbine MXOne. This unique system has a 360° operating range and enables the highly precise application of water mist from a significant and safe distance. In the event of a fire, the water mist absorbs a huge amount of energy, cools particularly effectively and reaches hidden fire sources better than classic monitors. It binds flue gases, pollutants and odors, and is able to exert its efficiency quickly over large areas. The effectiveness of the turbine has been examined and confirmed in full-scale fire trials conducted by independent bodies, including DMT.

MXOne can be operated with potable water, seawater and with/without foaming agents. Spray patterns can range from a fine water mist to a full jet. The firefighting system reaches a flow rate of up to 4,000 liters per minute. MXOne can be aimed at a hot spot either fully automatically or manually via remote control. Thanks to a smart operating system, a single turbine can supply water alternately to two or more neighboring areas. Consequently, several fires can be fought in parallel, or nearby facilities threatened by fire can be specifically cooled in a targeted manner. The turbine can be easily integrated into existing plants and is suitable for use in areas with temperatures ranging from -15°C to +55°C.

A decisive innovation: throw distance
MXOne has the unique ability to fight a fire with water mist from a significant distance. The turbine is able to offset the susceptibility of small droplets to external factors such as crosswinds or headwinds using a smart control system and activating a supporting air stream. Furthermore, the system can be flexibly adapted to meet almost any challenge posed by different fire scenarios.

Efficient firefighting with water mist
When extinguishing a fire with water mist, the water is atomized under high pressure, meaning the smallest of water droplets and a larger reaction surface are formed that absorb heat. When water evaporates, its volume is increased many times over, thus displacing the oxygen at the source of the fire. The smothering effect fights the fire directly. The cooling aspect of the water mist protects people and property from the effects of heat. The volume of water consumed during the firefighting effort as well as the consequential damage caused by the water are extremely low.

Maximal flexibility in positioning and application
The control and direction of the extinguishing turbine can be done fully automatically, as follows: Information from at least two fire detectors (e.g. UniVario industrial fire detectors or infrared cameras) is assessed in the fire alarm and control panel and the location of the source of the fire is accurately determined before MXOne is activated. Alternatively, manual control of the turbine is always an option. Both stationary and mobile control variants can be implemented according to the operator's requirements.

Project Partner of the German Rescue Robotics Center

Supported by the German Ministry of Education and Research (BMBF)

As the second largest fire protection company in the world, Minimax Viking GmbH supports the German Rescue Robotics Center (Deutsches Rettungsrobotik-Zentrum) in Dortmund. As the only project partner from the fire protection sector, Minimax Viking brings decades of experience in fire protection research.

Today marked the launch of the new specialist center on the former industrial site “Phoenix West” in Dortmund. Here, mobile robot systems for civilian hazard prevention are to be researched and developed. One of the center’s main features is the so-called “living lab” with in- and outside trial areas where the systems, together with their users, can be tested for their operational suitability in various scenarios.

The international fire protection company Minimax Viking has been working in fire protection research for decades. The Minimax fire protection research center celebrated its fiftieth jubilee in July of this year. “As one of the few private fire protection research centers in Germany, it is the biggest of its kind in Europe and carries out cutting-edge research into safety,” explained Klaus Hofmann, Chairman of the Executive Board. Minimax was the first company in Germany that used its own research center to expand its competency in the development of fire protection solutions. “This focus on innovation is characteristic of Minimax and remains a large part of the company culture,” Hofmann continued.

The German Rescue Robotics Center is aiming to gain international recognition. For the first time in Germany, emergency forces, researchers and industry will work together to develop autonomous rescue robots and a robotics task force acting on a national and an international level. They will compile testing and inspection criteria in order to guarantee the standardization and certification of different robot systems in the future. The basis is built on the four lead scenarios: fire, collapse and burial, detection of dangerous substances and flood, as well as the ensuing challenges for rescue robotics.

The starting point for the specialist center is the increased complexity of the challenges encountered by authorities and organizations with security responsibilities as part of their everyday tasks. Despite good training, mature, tactical concepts and reliable safety equipment, every year numerous members of emergency forces around the world are injured or killed at work. As technical development progresses it is, however, conceivable that mobile robotic systems will increasingly be able to take on tasks in the future, in order to make the handling of operations more effective and safer for emergency forces, endangered people and personal protective equipment.

The requirements from operational practices will be used to develop the rescue robots. Beyond the initiation and funding phase, a scientifically oriented specialist center is to be developed in order to make more efficient robotic technology available to rescue teams on the market.

The Project
The project is being supported with an initial investment for four years by the German Ministry of Education and Research (BMBF) and will be led by an interdisciplinary and well-known association of users, industry, universities and research institutes. The funding is part of the German government's “Research into Civilian Safety 2012- 2017”, as part the topic area “Civilian Safety - Innovation laboratory / specialist centers for robotic systems in hostile environments” (Funding code13N14852 to 13N14863)

Recycling industry finds out at Recycling-Technik in Dortmund
November 5, 2018 - Solutions

Fire protection as a competitive advantage

Recycling industry finds out at Recycling-Technik in Dortmund

The rapidly growing industry of recyclable material processing finds itself confronted by a high level of fire risk. People, environment and companies are regularly threatened by large fires. Many business operations are now upgrading and in doing so are attaching importance to a comprehensive fire protection concept. On 07-08/11 at Recycling-Technik in Dortmund, Minimax is showing what such a concept should look like (hall 7, stand T26). 

Delivery and storage areas - detecting hot spots

There is a risk in these areas that stored substances will auto-ignite. Here, internal areas are particularly at risk, since dust can create an explosive atmosphere. In order to detect potential ignition hazards in good time, the recyclable material storage areas are constantly monitored. Thermography systems with infra-red cameras are used for this wide-area early detection of fire. They detect objects by their radiative heat transfer and spot critical temperature developments. If there is a threat of ignition, a signal is transmitted to the connected fire detection control panel. Extinguishing monitors are aimed at the target manually or via remote control. They provide effective fighting of the so-called hot spot via water enhanced with film-forming foam compound. Active smoke aspiration systems and industrial flame detectors provide extra security in internal areas. They can also cope with particularly tough environmental conditions and dependably detect potential fires. Their signals are sent to a fire detection control panel which evaluates them and in an emergency activates automatic extinguishing by a deluge system.

Mechanical conveyor systems - safety in motion

During the sorting process, recycling materials are continually transported via conveyor belt systems. This means multi-faceted risks: overheated roller bearings, sparks which may occur during maintenance- or welding work, or auto-ignition of the material to be conveyed. The combined installation of industrial flame detectors and multi-sensor combustion gas detectors is a proven fire-safety measure for dependable and early detection of a fire. Minifog ProCon water mist systems are a particularly efficient solution for direct fire fighting. After a fire has been detected, the section of the conveyor belt is extinguished and operation can be continued without major downtime. The crucial advantage of this extinguishing system compared with conventional water spray systems is the significantly lower use of extinguishing water.

Pneumatic suction and conveyor systems - no opportunity for sparks

Wherever flammable materials are pneumatically transported, there is an increased risk of fire. This applies particularly to the material mix in pneumatic suction and conveyor systems in the recycling process. Sparks, hot particles or glowing embers in the processing machinery which arrive in the delivery systems have risk potential. Dust explosions are also possible. Functionally monitored spark detectors which react to infrared radiation of potential sources of ignition flying past, ensure dependable and above all immediate detection. If the spark detectors identify potential sources of ignition in the materials being conveyed, a signal is sent to the control panel. This unit then activates the automatic extinguisher solenoid valve in milliseconds. The extinguishing water is released and introduced into the volumetric flow via self-closing nozzles. The glowing particles fly into the water mist formed by the nozzle. Particularly innovative spark detectors, such as the UniVario YMX5000 detector range, themselves monitor their optical system with regard to dirt or damage at regular intervals. Functions such as these increase operational safety in the challenging areas of application in a recycling facility.

For an integrated fire protection concept however, all areas of a recycling complex must be thought of. For this reason separation and crushing facilities, agglomeration presses or even ancillary areas such as server or control rooms and office buildings must also be taken into consideration.

We look forward to welcoming you to our stand, T26 in hall 7 at Recycling-Technik in Dortmund.
